So how about this: EITHER something is determined by the sum of atomic parts and rules OR it is truly random. There are two mechanisms which make events seem random in ordinary life. One is the difficulty of actually making the required measurements, finding the appropriate rules and then doing the calculations. Classical chaos may make this practically impossible, but we still understand that the event (such as a coin toss) is fundamentally deterministic, and the randomness is only apparent. The other mechanism is quantum randomness, for example in the case of radioctive decay. In a single world interpretation of QM this is, as far as I am aware, true randomness. In a no-collapse/ many worlds interpretation there is no true randomness because all outcomes occur deterministically according to the SWE. However, there is apparent randomness due to what Bruno calls the first person indeterminacy: the observer does not know which world he will end up in from a first person viewpoint, even though he knows that from a third person viewpoint he will end up in all of them. I find the randomness resulting from first person indeterminacy in the MWI difficult to get my mind around. In the case of the chaotic coin toss one can imagine God being able to do the calculations and predict the outcome, but even God would not be able to tell me which world I will find myself in when a quantum event induces splitting. And yet, I am stuck thinking of quantum events in the MWI as fundamentally non-random.
